TVS - Diodes

The JANTX1N6120 is an integrated circuit (IC) designed for providing Transient Voltage Suppression (TVS) protection. It is a multi-channel, ultra-low-power, reverse transistor-transistor logic (RTL) level diode device. This diode is particularly well-suited for these modern pulse-width-modulation (PWM) devices, which are becoming increasingly popular in automotive, medical, and consumer applications.

Application Field

The JANTX1N6120 is specifically designed for automotive, medical, and consumer applications. More specifically, it is ideal for providing protection against electrostatic discharge (ESD). It is also applicable for surge transient suppression (STS) and temperature protection over voltage (TOV) protection.

In automotive, it is used as a surge protection for communications and power lines, as well as power transistors. In medical applications, it is used for protecting X-ray tubes from overvoltage, while in consumer applications, it is used for preventing power supply failures.

Working Principle

The JANTX1N6120 operates on the principle of reverse polarization and short circuit current limiting. It contains an array of ultra-low-power diodes, each with a breakdown voltage of 6V, connected in parallel. The diodes are connected so that the cathode of each diode is connected to the anode of the corresponding diode in the adjacent diode trap.

When an over-voltage threshold is exceeded, the transistors quickly turn off and the circuit is left short-circuited. This limits the surge current and thus protects the circuit components from destruction. The reverse polarization principle also helps protect the circuit components from over-voltage damage.

The TVS device can be used to protect sensitive digital circuit elements like microprocessors, integrated circuits, and other components from destruction due to electrostatic discharges or other transient surge events. The device can be used in any circuit where protection against dangerous, destructive transients is required.
